B: It is funny there is a market for TurboHercules, where people use it when their Mainframe crashes. I thought Mainframe never crashes? If there is market for this product, it means Mainframes crashes.

You're kidding right!? There's more to disaster recovery than crashes. All computers are susceptible to external events, i.e. power failures due to mother nature... UPS doesn't last forever, and is useless if the network is down. Don't pretend that Hercules is around because mainframes have more down time than every other platform.
